Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. COA of Formula: C8H7BrO. Introducing a new discovery about 189035-22-1, Name is 6-Bromo-2,3-dihydrobenzofuran
The synthesis and structure-activity relationships of a series of 5,7-diarylcyclopenteno[1,2-b]pyridine-6-carboxylic acids are described. Our efforts have been focused on modification of the aryl ring at the 5-position and the alkyl substituent at the 2-position of the bottom 4-methoxyphenyl ring in an effort to develop orally available ETA selective antagonists with safer profiles in terms of the P-450 enzyme inhibitory activity. Incorporation of a hydroxymethyl group as an alkyl substituent in methylenedioxyphenyl and 6-dihydrobenzofuran derivatives led to the identification of orally bioavailable ETA selective antagonists 1f and 7f. These compounds also showed not only excellent binding affinity (IC50<0.10nM, more than 800-fold selectivity for the ETA receptor over the ETB receptor) but also sufficient oral bioavailability, 48% and 56%, respectively, in rats. Furthermore, these compounds did not exhibit either competitive or mechanism-based inhibition of human cytochrome P450 enzymes. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C8H7BrO, you can also check out more blogs about189035-22-1
